PRE COMMISSIONING CHECK
Before commencing the commissioning procedure, refer to the design drawing for correct air flows. See Figure 5.
NOTE: Extract air and supply air volumes will not always be equal, therefore, when setting up, the extract system should
be the datum.
Ensure that the exhaust and supply grilles or valves are open.
Check the airflow at the grilles or valves, and adjust to suit the design figures.
For bathroom extract this unit is factory set for 30 m
3
/h in trickle mode and 76 m
3
/h in boost mode, based on the system
configuration in Figure 3.
NOTE: If changes are required to meet differing system specifications the following on site adjustments can be made.
FAN ADJUSTMENT FOR EXTRACT (I.e. FROM BATHROOM)
At the start of any fan adjustment, you MUST check the trickle airflow rate and boost airflow rate before commencing.
INSTALLER MODE
To start installer mode, press installer mode switch.
When installer mode is ready the red LED indicator will start flashing every second. Now extract and supply fans can be
adjusted.
When out of installer mode the Red LED will stop flashing.
NOTE: When bathroom light is switched OFF there is no switch live.
When bathroon light is switched ON switch live is present.
TRICKLE AIRFLOW ADJUSTMENT ONLY
Trickle airflow rate needs to be 30 m
3
/h. To adjust this the bathroom light should be OFF.
NOTE: During the adjustment do not switch (i.e. bathroom light) ON at any point.
Put unit into installer mode.
To adjust the TRICKLE setting turn RV1 (extract fan) and RV2 (supply air fan clockwise

to increase the airflow rate and
anticlockwise

to decrease the airflow rate.
When it is set to 76 m
3
/h, do not take the unit out of installer mode and to set BOOST AIRFLOW you must close its switch.
Boost airflow rate needs to be 76 m
3
/h. To adjust this switch should be ON (switch live).
NOTE: During the adjustment do not switch OFF at any point.
To adjust the BOOST setting turn RV1 (extract fan). (In default mode only the extract fan will boost.)
When it is set to 76 m
3
/h, take the unit out of installation mode. Red LED will stop flashing.
SETTING SPEED POSITIONS
- After setting the required airflows in auto mode turn the switch to
position 1.
- Ensure unit is out of installer mode and switch live is OFF.
- Rotate the potentiometer 1 (on reverse side of the switch) to the
required position to provide the required airflow.
- Turn switch to position 2.
- Ensure unit is out of installer mode and switch live is OFF.
- Rotate the potentiometer 2 (on the reverse side of the switch) to the
required position to provide the required airflow.
NOTE : in manual modes 1 & 2, if the switch live is turned ON, both
fans turn to the setting which was set in the AUTO mode.
